Description of my issue:

I have just purchased Matukio having used Seminar in version 1.5 of Joomla. I tried to load the extension pack and get an error unable to open archive. I tried to extract using a tool on the mac and get an error as shown, I have also tried an older version 4.0.1

Your help would be appreciated
